A red fox shows its ingenious method of catching rodents that it can hear, but not see beneath the snow. Join NATURE for a breathtaking look at wintertime deep within America's first national park. (02:04)

What big ears you have, my dear. This tiny fox has huge ears that help it to pick out its next meal. What will it be this time - lizard, scorpion, or some tasty bug? But no amount of super-powers can save a potential suitor from the wrath of a domine...ering father; looks like a little persistence is in order. (02:13)[more]

A great lesson in adaption and, if students use if with the story of Wolf 527 from Yellowstone, can see the differences when man and animal come in contact. A... good video that also shows how little we know about wolves. (01:21)[more]

The clip is under t...wo minutes, but shows that wolves do not attack the strongest. The lesson for students here is to notice how the wolves work as a team for success. Question: Did man learn this hunting technique from wolves? (01:20)[more]
